Prenatal Vitamins

Prenatal supplements consist of a variety of vitamins and minerals. During pregnancy, a woman’s daily intake requirements for certain nutrients, such as folic acid (folate), calcium, and iron will increase. Vitamins and minerals such as iron, calcium, and folic acid are vital for proper fetal growth, development and healthy adult living.

To help increase your chances of creating a healthy and nutritious environment for your baby to develop, it is important that you establish a well-balanced diet and exercise routine before you get pregnant. If you choose to supplement your diet with synthetic nutrients, be sure to keep track of daily amounts that you take and let your health care provider know.

Choose Wisely

Multivitamin combinations can vary depending on the nutritional focus. For example, some manufacturers will create multivitamins that have a higher amount of iron than usual, targeting women who are prone to iron-deficiency anemia. While certain prenatal multivitamins are only available by a doctor’s prescription, there are many of them are available over the counter. Keep in mind that it is possible to jeopardize your baby’s (or your own) health by taking inappropriate amounts of synthetic vitamins, so be sure your health care provider is aware of any supplements you are taking.

Talk to Your Health Care Provider

Avoid taking several different supplements unless under a health care provider’s supervision, instead take one multivitamin that includes a variety of needed nutrients in one dose. Combining supplements (such as taking a folic acid supplement along with your multivitamin, etc) can raise concerns because you run the risk of overdosing on a particular nutrient. Taking more than 100% the RDA of any nutrient should be avoided during pregnancy unless under the direction of your health care provider.
If your typical daily diet consists of unprocessed foods, fruits, a colorful variety of vegetables, whole grains, lentils, and plenty of water, then you will likely have sufficient vitamins and minerals already in your body. As long as you are eating a well balanced diet, you need not fear overdosing on nutrients found naturally in foods (although some studies have shown symptoms of toxicity after large consumption of animal organs, like liver). However, supplements (synthetic vitamins and minerals) are a different story. They contain higher doses in concentrated form, which can be dangerous if taken in improper amounts. Always let your health care provider know what nutritional supplements you are taking. Consider taking your supplement bottles with you to your first prenatal visit.
Synthetic vitamin supplements can be helpful ways of including vital nutrients in your daily meals. Vitamins and minerals are essential to healthy development of your baby, as well as your own physical health. Be sure to speak with your health care provider about nutrition before you conceive if you are planning to get pregnant in the near future, or as soon as you know you are pregnant.
